Two acute triangles have perimeters of 20 meters and 100 meters respectively. how many times greater is the perimeter of the larger triangle?

÷÷Im not sure but I think its 5 because I did 100÷20=5. so ya.

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
